In a nationwide retail chain, IT deploys the WIC-2T-2-Port Serial WAN Interface Card on Cisco ISR routers at five regional offices to aggregate dual T1/E1 links into a single logical circuit. This configuration delivers 2× the bandwidth, active/standby line failover and real-time voice/data convergence, resulting in 99.99% uptime, 30% lower per-site telecom costs and streamlined centralized inventory management.
A food processing plant integrates proprietary PLC and SCADA systems into its corporate MPLS backbone by installing the WIC-2T-2-Port WAN card on modular Cisco switches. The dual-port serial interfaces bridge RS-449/RS-232 field controllers across T1/E1 circuits, ensuring sub-50 ms polling latency, simplified network architecture and a 25% reduction in maintenance overhead for critical operations monitoring.
A global bank implements hot-swappable WIC-2T-2-Port cards in paired ISR routers across primary and DR data centers to establish mirrored E1 circuits for transaction replication and call-center voice traffic. The solution enables sub-second failover, non-disruptive module replacement and compliance with strict SLAs, delivering 99.95% availability and secure real-time disaster recovery orchestration.

We use the WIC-2T for dual T1 connectivity. It's been a reliable solution, providing stable and fast data transfer for our network.
The WIC-2T is an excellent addition to our system. It supports two T1 connections, ensuring stable, high-speed communication across our devices.
The Cisco WIC-2T is a 2-port serial WAN interface card that provides dual simplex or single full-duplex serial connectivity for T1/E1, DDR, HDLC, PPP, Frame Relay and other WAN protocols.
The WIC-2T supports data rates from 56 Kbps up to 2.048 Mbps, enabling T1/E1 connectivity and flexible bandwidth allocation.
The WIC-2T is compatible with Cisco Integrated Services Routers (ISR) 1800, 2800, 3800, 3900 series and select Cisco 7200 series platforms that feature a WIC slot.
Each WIC-2T port uses an RJ-48C connector. You must use a standard serial CSU/DSU or smart serial cable to connect to the WAN service provider.
Power down the router, insert the WIC-2T into an available WIC slot, secure the card with the slot blank cover screw, then power on and configure the interface in IOS.
No. The WIC-2T is not hot-swappable. You must power down the router before inserting or removing the card.
The WIC-2T supports standard serial WAN protocols including HDLC, PPP, Frame Relay, X.25, and DDR, plus specialized features like multilink PPP and Frame Relay subinterfaces.
Yes. The WIC-2T can operate as two simplex ports or one full-duplex port, providing flexible connectivity options.
Yes. You need Cisco IOS software releases that support the WIC-2T, typically Cisco IOS 12.4 or later for ISR platforms. Verify feature set compatibility before deployment.
Installation limits vary by platform. For example, Cisco 2800 and 3800 series routers support up to three WIC slots, while the 3900 series supports up to two WIC-2T cards.
Maximum distance depends on your CSU/DSU and service provider; the WIC-2T itself supports standard T1/E1 electrical levels up to 1.8 km without a repeater.
Yes. The WIC-2T supports internal network clocking or external clocking via the CSU/DSU, ensuring reliable synchronization for T1/E1 services.
The WIC-2T consumes approximately 4 W of router power. Check your router’s power budget to ensure adequate capacity.
Yes. The WIC-2T is covered by Cisco’s limited hardware warranty and is eligible for Cisco SMARTnet® service and support.
No. The WIC-2T provides two independent serial ports; it does not support channelized DS1/E1 interfaces. For channelized services, use a Channelized WIC.
In Cisco IOS EXEC mode, enter global configuration, use interface serial <slot/port>, assign IP address, encapsulation (e.g., hdlc or ppp), and no shutdown.
